|Ngi pdiangsngewbha ia phi sha ka ''' Spoken Tutorial''' halor ka ''' Special variables in Perl.'''
|-
|00:04
|Ha kane ka jinghikai, ngin ia pule shaphang ki:
'''Global special variables'''
'''Special command line variables'''
'''Global special constants'''.
|-
|00:13
|Na ka bynta kane ka jinghikai, nga pyndonkam da ka:
'''Ubuntu Linux 12.04''' operating system
'''Perl 5.14.2''' bad ka
''' gedit''' Text Editor.
Phi lah ban pyndonkam da kano kano ka '''text editor''' katkum ka jingkwah jong phi.
|-
|00:27
|Kum ka jingdonkam ba hashwa, phi dei ban don ia ka jingtip shaphang ka '''Perl''' Programming.
|-
|00:32
|Lada phim don, sngewbha leit sha ka jinghikai ba iadei ha ka ''' Perl''' spoken tutorials ha ka ''' spoken tutorial''' website.
|-
|00:38
|Kiei ki ''' special variables'''?
|-
|00:41
|'''Special variables''' kidei ki predefined variables kiba don ia ka jingmut ba kyrpang ha ka '''Perl'''.
|-
|00:46
|Kine kim donkam ban initialized hashwa ban pyndonkam.
|-
|00:50
|Ia kine la pyndonkam ban bat bad buh ia ki results jong ki searches,'''environment variables''' bad '''flags''' ban control ia ka '''debugging'''.
|-
|00:58
|Nyngkong, ngin ia pule shaphang ki''' Global special variables.'''
|-
|01:02
|'$_': (Dollar Underscore). Une udei u ''' special variable''' ba lah ju kham pyndonkam.
|-
|01:06
|'''$_''' - '''Dollar Underscore''' udei u '''default parameter''' na ka bynta ki '''function'''s bad pattern-searching '''string'''s.
|-
|01:14
|To ngin ia pyrshang ban sngewthuh ia ka jingpyndonkam jong u '$_' (Dollar Underscore) variable da kaba pyndonkam ia ka sample program.
|-
|01:20
|Ngan plie ia ka ''' special dot pl file''' kaba nga lah dep shna lypa.
|-
|01:26
|Leit sha ka '''terminal''' bad type: ''' gedit special dot pl ampersand ''' bad shon '''Enter.'''
|-

|'''special dot pl''' file ka lah plie mynta ha ka '''gedit'''. Type ia u code kumba la pyni ha ka screen. To ngan batai mynta ia u code.
|-
|01:42
|Don 2 tylli ki '''foreach '''loops hangne. Baroh kine ki '''foreach ''' loops kin sa execute ia kajuh ka result.
|-
|01:49
|Ha man ka jingiaid jong ka loop, ka string kaba mynta ka lah shah buh ha u '$_'.
|-
|01:54
|Bad la pyndonkam ia ka da ka print statement, da kaba lah long hi. U '''$_ (Dollar Underscore)''' u save ia ka jingpyndonkam jong uwei pat u variable '''$color''' uba tam.

|-
|02:18
|Mynta, to ngin ia peit ia kawei pat ka nuksa ban batai kumno u '$_' (Dollar Underscore) variable _u long implicit.
Leit biang sha ka '''special dot pl file'''.
|-
|02:27
|Type ia u code kumba la pyni ha ka screen.
|-
|02:30
|Kane ka program ka read ia ka text file "first.txt" kawei pa kawei ka lain. Nangta ka loop lyngba ka '''DATA''' file, haduh ba baroh ki lain lah read lut.
|-

|'''Array operation'''s kum ka '''pop/shift ''' lah ban leh ha kane ka variable, kumba ngi leh ha ka normal arrays.
|-
|03:13
|Ngan pyni ia ka nuksa na ka bynta kane. To ngin ia phai biang sha ka '''special dot pl file''' sa shisien.
|-

|Type ia u code kumba la pyni ha ka screen.
|-
|03:22
|Kane ka program kan pynphai ia u value ba heh duh napdeng ar tylli ki number.
'''@_ (At the rate underscore)''' udei u '''local''' array uba buh ia ar tylli ki arguments, dollar 'a' comma dollar 'b'.
|-
|03:35
|Kata kadei, lah buh hapoh u '''dollar underscore index of zero''' bad '''dollar underscore index of one'''
|-
|03:43
|Ka '''print''' statement ka print ia u number ba heh duh napdeng ki numbers ba lah ai.
|-
|03:47
|Shon ''' Ctrl+S''' ban '''save''' ia ka file.

|To ngan batai ia u code. Ka lain ba nyngkong ka declare ia ka array jong ki number.
|-
|06:02
|U '''numerical comparison operator ''' un sa ia nujor ia ar tylli ki values jong ki number.
|-
|06:08
|'''Dollar a''' bad '''dollar b ''' kidei ki '''special package local variables''' ha kaba ki values badei ban ia nujor lah sei.
|-
|06:16

|'''dollar dollar''' udei sa uwei pat u '''special variable.''' Une u buh ia ka '''process ID''' jong ka '''Perl interpreter''', kaba run ia kane ka script.
|-
|07:26
|Ia u '''diamond operator''' la pyndonkam ban read ia man ki lain na ki file ba lah ai ha u '''command line'''.
|-
|07:32
|To ngin ia peit ia ka nuksa na ka bynta kane.
|-

|Kane kadei ka text kaba ngi don ha ka'''sample dot txt''' file.
|-
|08:11
|Lada ym don kino kino ki files ba lah ai, ka read na ka '''standard input''' kata na ka keyboard.
|-
|08:17
|'''Perl''' kadon ia ka array '''at the rate capital A R G V ''' u variable ba kyrpang. Une u buh ia baroh ki values na ka '''command line'''.
|-
|08:27
|Ynda pyndonkam ia u '''at the rate capital A R G V, ''' ym donkam ban declare ia ki variables.

|Ki values na ka '''command line''' ki lah buh hi dalade ha une u variable.
|-
|08:37
|To mynta ngin ia phai sha ka '''Global Special Constants.'''
|-
|08:41
|'''underscore underscore E N D ''' (baroh ha ki dak heh )'''underscore underscore''' ka pynithuh ia ka logical end jong ka program.
|-
|08:50
|Kano kano ka text kaba bud da ka '''special variable ''' ka shah iehnoh hadien kane ka statement.
|-

|-
|09:44
|Type ia u code harum kumba la pyni ha ka screen. To ngan batai mynta ia u code.
|-
|09:50
|Ki literals ba kyrpang "PACKAGE, FILE, LINE" ki ieng ha ka jaka ka kyrteng ka package, ka filename ba mynta bad u line number, ha kata kapor ha ka program.
|-
|10:00
|To ngin ia '''execute''' ia ka program.
|-
|10:02
|Phai biang sha ka terminal bad type: '''perl specialconstant.pl''' bad shon ''' Enter'''.
|-
|10:09
|Ngi iohi ia ka kyrteng jong ka package ba mynta, ka filename bad ka line number jong ka program jong ngi.
|-
|10:15
|Da kane ngi lah poi sha kaba kut jong kane ka jinghikai. To ngin ia batai kyllum.
|-
|10:19
|Ha kane ka jinghikai, ngi lah pule shaphang katto katne ki '''special variables''' kiba shait kham pyndonkam ha ka '''Perl'''.
|-
|10:25
|Kum ka kam na ka bynta jong phi, leh ia kane harum. Thoh ia ka '''Perl''' script ban '''sort''' ia ki array harum jong ki numbers ha ka order ba kiew bad ba hiar.
|-
|10:34
| Kynmaw: Na ka bynta ka order kaba kiew, pyndonkam ia u code harum na ka bynta ban ia nujor.
|-
|10:39
| Print ia ka result ba lah sort da kaba pyndonkam ia ka '''while''' loop bad '''special variable $_ (Dollar Underscore)'''.

|Ka video ha ka link harum ka kyllum lang ia ka Spoken Tutorial project. Sngewbha download bad peit ia ka.
|-
|10:56
|Ka kynhun jong ka '''Spoken Tutorial''' project ka pynlong ia ki workshops bad ka ai certificate sha kito kiba pass ha ki online tests.
|-
|11:03
| Na ka bynta ki jingtip ba bniah, sngewbha thoh sha ngi.
|-
|11:06
|Ia ka Spoken Tutorial project la bei tyngka da ka NMEICT, MHRD, Sorkar India.
